Homicide detectives investigating the shotgun killing of an 18-year-old Rialto woman say they hope to refile their case with prosecutors by the end of the week.

The San Bernardino County District Attorney’s Office rejected the criminal case against Craig Stevens Luke, 20, of Redlands and Devyn Jusmond Berry, 20, of Muscoy on Monday. Sheriff’s deputies arrested the pair following the shooting of Lurissa Holcomb, but they have since been released from jail.

Prosecutors who reviewed the case said detectives needed to gather more evidence before charges could be filed.

“The DA just wants to make sure they file the appropriate charge, which could range from a manslaughter, negligent discharge of a firearm, second degree murder and anything in between all that,” said San Bernardino County sheriff’s Sgt. Frank Bell.

Investigators say Luke fired a shotgun at Holcomb, striking her in the back of the neck at a Nolan Street home July 29 in Muscoy. Luke told detectives he didn’t know the gun was loaded. After the shooting, Berry took the gun and tried to hide it, sheriff’s officials said.

Prosecutors said they needed additional information from witnesses to the shooting.

“They’re just waiting on us to finish up our entire investigation and hand it back to them, which I hope will be done by the end of the week,” Bell said.
